Harbey; and commissioned 15 December 1953, Lieutenant Commander J. F. Butler in command. She was reclassified MS0-432 on 7 February 1955' (transcription prints letter-O 'MS0-432'). Assigned to Mine Division 91, Squadron 9, Mine Force, Pacific Fleet, home port Long Beach - training with ships, aircraft, soldiers, Marines, and foreign minesweepers; Far East cruise 1957-58 (Japan, Korea, Taiwan; exercises with Chinese Nationalist and Korean navies); similar cruise first half of 1960; 'Pacific Festival' at San Francisco September 1960; 'received a yard overhaul during the remainder of the year' - yard not named.

- Local-press shipyard history documents the builder: Colberg Boat Works, 848 W. Fremont St., Stockton, operating from the late 1890s into the early 1990s, built 'several scores of ships for the US Army and Navy, including minesweepers, launches, rescue ships, tugs and sub chasers' - among them USS Dynamic (MSO-432) and sisters USS Engage (MSO-433) and USS Embattle (MSO-434).

- Published asbestos-litigation order names this hull: plaintiffs alleged decedent John Dale Wineland was exposed to asbestos contained in Crane Co. products while aboard USS DYNAMIC, USS LOYALTY, USS TUSCALOOSA, and/or USS ESTEEM during a 1963-1984 Navy career; he 'worked primarily in the engine rooms of the ships to which he was assigned, repairing and maintaining machinery and equipment such as diesel engines, pumps, air compressors, and valves'; he developed mesothelioma and died in 2018. The court GRANTED Crane Co. summary judgment for failure to produce admissible evidence that exposure to asbestos from Crane products was a substantial contributing factor.

- Motion-stage product identification recorded for this hull verbatim: 'There is evidence that Alfa Laval purifiers were installed in the aft engine rooms of the DYNAMIC, LOYALTY, ESTEEM, PLEDGE, and TUSCALOOSA ... that DeLaval lube oil pumps serviced the main propulsion reduction gears installed on DYNAMIC, LOYALTY, ESTEEM, and PLEDGE' (citing Dkt. #394-2 at 15, 394-6 at 46, 394-7 at 17, 394-8 at 67). Wineland's service aboard DYNAMIC is dated 1963-1966 in the order. Defense expert Captain Arnold Moore opined that enginemen 'took apart and cleaned diesel oil purifiers as a routine part of their duties.' The order nonetheless GRANTED summary judgment: plaintiffs could not show Mr. Wineland was exposed to asbestos from an Alfa Laval product aboard any vessel, and Captain Moore 'could not say that Mr. Wineland was exposed to asbestos from an Alfa Laval product.'

The same order resolves the claims against Alfa Laval in the defendant's favor - a merits-level negative for this plaintiff. Equipment brands so identified are carried as litigation allegations only; they do not enter product_normalized, which reflects era-inference categories instead.

- Finding type

- Finding
- GAO documented the Navy's asbestos program: product specifications for thermal insulation were revised to asbestos-free in 1973, but already-purchased asbestos materials continued to be installed and 'some ships were delivered with asbestos insulation as late as May 1978'; the Navy's October 1975 policy removed only damaged or repair-necessitated insulation, modified in January 1979 to selective replacement in high-maintenance areas. This hull's construction (1951-53) and entire U.S. commission (1953-71) fall inside the asbestos-specification era the report documents.

- Finding
- Era-typical asbestos applications aboard a 1950s wooden-hulled diesel-propelled ocean minesweeper, inferred rather than proven for this hull: diesel exhaust-system and muffler lagging on the four main engines and generator plant; machinery gaskets and packing; electrical-cable insulation; deck coverings and cements; brake linings on winches, windlass, and minesweeping gear. Because the documented plant is diesel with no boilers or steam distribution, the boiler-room and steam-line insulation envelope emphasized for steam combatants does not apply - the residual envelope concentrates in engine exhaust and machinery spaces.

Bruhn's mine-warfare award compilation indexes USS Dynamic (MSO-432) for Market Time coastal patrol periods 1 October 1965 - 30 June 1966, 1 September 1967 - 31 May 1968, and 29 August - 15 October 1970; an unofficial MACV-summary-referenced ship list carries 'USS Dynamic MSO-432 Coastal patrol unit' for 1966. Dynamic does NOT appear in the May 2011 revision of the VA presumptive-exposure (Agent Orange) ships list - full-text verified - consistent with offshore patrol rather than inland-waterway or docking entries.

Absence from the May-2011 VA list speaks to Agent Orange presumption categories only - it is neither evidence of, nor evidence against, Vietnam operations, and later list revisions were not retrievable.

- Finding type

Carried as 'Agile/Aggressive class' with the split noted, not adjudicated. (b) 1967 division: NavSource records a September 1967 change to Mine Division 71 (Dynamic, Engage, Impervious, Inflict, Fortify); Wikipedia repeats 'Mine Division 91' for the same event and ship list - unresolved, MinDiv 71 carried as the change target. (c) Specs: complement 74 (DANFS) vs 80 (NavSource); displacement 620 (DANFS) vs 630 lt/755 fl (NavSource); speed 10 kts (DANFS) vs 14 kts (NavSource). (d) Spain transfer: NavSource/official chain read sold 17 July 1971; the Stockton Record reads 'sold to Spain in 1974' - consistent with the secondary-documented loan-then-purchase structure (delivered 1971, purchased 1974, matching the 1 Aug 1974 U.S. strike). (e) DANFS transcription prints 'MS0-432' (letter O) for MSO-432.
